VCP-VCF Administrator 2024 Question 180
Single answerAn administrator is managing a VMware Cloud Foundation environment and has been tasked with taking snapshots of virtual machines before performing maintenance. The administrator wants to understand the impact of performing different snapshot operations. Which of the following statements about snapshot operations is accurate?
- A
Deleting a snapshot consolidates the snapshot delta file into the base disk, potentially causing a temporary performance impact.
- B
Reverting to a snapshot removes all subsequent snapshots and restores the virtual machine to its original state.
- C
Creating a snapshot increases the size of the virtual machine's base disk file immediately.
- D
Consolidating snapshots is only required when there are orphaned snapshot delta files.
Show answer and explanation
Correct answer: A
Explanation
Understanding the impact of snapshot operations is essential for managing VMware Cloud Foundation. Deleting a snapshot consolidates changes from the delta file into the base disk, which can cause a temporary performance hit due to the intensive I/O operations. This knowledge helps administrators plan maintenance and snapshot operations effectively.
- A. Correct.
Correct: Deleting a snapshot merges the changes stored in the delta file into the base disk, which can result in a temporary performance impact on the environment due to the I/O operations involved.
- B. Incorrect.
Incorrect: Reverting to a snapshot restores the state of the virtual machine to the snapshot point but does not remove subsequent snapshots. Subsequent snapshots remain intact.
- C. Incorrect.
Incorrect: Creating a snapshot does not increase the size of the base disk file immediately. Instead, it creates a delta file that grows over time as changes are made to the VM.
- D. Incorrect.
Incorrect: Consolidating snapshots is required to merge snapshot delta files into the base disk, but it is not only required for orphaned files; it can also be necessary in cases of multiple snapshots.
